There will be brief impacts to traffic Wednesday morning while Hawaiian Electric Company transports a large transformer from Kapolei to Palolo Valley.

The move will happen between 9 a.m. and 11 a.m.

An 80-ton transformer will inch it's way from the Ewa Nui Substation, through parts of Oahu and end up at the Pukele Substation.

The over-sized load convoy is expected to travel 10-15 miles per hour through a carefully planned route, and 5 miles per hour over bridges.

They are expected to cross over the Waikele Stream using the westbound bridge. Around 9:30 a.m., westbound traffic will be stopped on Farrington Highway between Waikele Road and Waipahu Depot Street.

"Between 10:30 and 11 a.m., the transport vehicle is expected to arrive at Pakele Substation, traveling along Palolo Valley’s narrow Carlos Long and Myrtle streets. Parking on those streets will be restricted, and traffic will be stopped as the transport passes," HECO said.
